BACKGROUND

The spectrum and backhaul resources of telecommunication networks are limited. As these networks communicate an increasing amount of data, congestion, delay, and failed connections become more common. Voice calls, video calls, and other real-time communications are often dropped, web pages load slowly, and movies must repeatedly pause in order for their buffers to refill. With such demands and limited resources, some priority must be given to certain types of network traffic. To provide such priority, telecommunication networks associate traffic with quality-of-service (QoS) classes. Such classes may refer to specific types of applications or service (e.g., voice calling, network browsing, etc.), different data types, different service categories, etc. Traffic of a higher priority QoS class may receive a better allocation of resources (e.g., frequency blocks, etc.) than traffic of a lower priority QoS class. Further, the QoS classes may be assigned different weights that affect the impact of the priorities. This weighting scheme, however, is static, with weights of QoS classes not changing with circumstances. For example, because of the static weighting scheme, traffic associated with a lower priority QoS class may receive a worse allocation of resources than necessary during a time when network services are not in demand.

DETAILED DESCRIPTION

This disclosure describes, in part, one or more SON components configured to determine QoS factors associated with QoS classes for a node of a telecommunication network based at least in part on performance metrics, network configuration, or network fault information. The one or more SON components may receive the performance metrics, network configuration, or network fault information from the node, and the performance metrics, network configuration, or network fault information may be associated with communication of traffic of the QoS classes by the node. Upon determining the QoS factors, the one or more SON components may transmit indications of the QoS factors to the node to enable the node to update its QoS class QoS factors. This reporting of performance metrics, network configuration, or network fault information and determining and updating of QoS factors may be performed repeatedly over time to optimize the QoS factors for the QoS classes at a node under different performance conditions. Such a dynamic scheme allows greater use of network resources during times with lower demand while carefully allocating such resources at times with higher demand.

Example Environment

FIG. 1 illustrates an example environment including SON component(s) and node(s) of a telecommunication network, the SON component(s) receiving performance metrics, network configuration, or network fault information from the node(s), determining QoS factors for QoS classes for the node(s) based on the performance metrics, network configuration, or network fault information, and transmitting indications of the QoS factors to the node(s). As illustrated, one or more computing devices 102 configured with one or more SON components (referred to hereinafter as “SON device(s) 102”) may include, among the SON component(s), one or more SON tools 104 configured to determine QoS factors 106 for QoS classes 108 associated with traffic 110 communicated by one or more nodes 112 of a telecommunication network 114. The SON component(s) of the SON device(s) 102 may also include a performance metrics, network configuration, or network fault information store 116 which receives and stores performance metrics, network configuration, or network fault information reported by the node(s) 112, a consolidation engine 118 to gather and utilize the performance metrics, network configuration, or network fault information, and a parameter configurator 120 to provide indications of the determined QoS factors to the node(s) 112. Transmission component(s) 122 of the node(s) 112 may update the QoS factors 106 based on the received indications and utilize the updated QoS factors 106 and QoS classes 108 in allocating network resources to different parts of traffic 110. Additionally, the SON component(s) of the SON device(s) 102 may include a SON portal 124 to enable configuration of the SON tools(s) 104.

In various implementations, the SON device(s) 102 may each be or include a server or server farm, multiple, distributed server farms, a mainframe, a work station, a personal computer (PC), a laptop computer, a tablet computer, an embedded system, or any other sort of device or devices. In one implementation, the SON device(s) 102 represent a plurality of computing devices working in communication, such as a cloud computing network of nodes. The SON device(s) 102 may belong to the telecommunication network 114 or may be external to but in communication with the telecommunication network 114. An example SON device 102 is illustrated in FIG. 2 and is described in detail below with reference to that figure.

The telecommunication network 114 may be any sort of telecommunication network of a telecommunication service provider and may include a core network and any one or more packet-switched access network(s), circuit-switched access network(s), or both. The access network(s) of the telecommunication network 114 may utilize 2G, 3G, 4G, 5G, Global System for Mobile Communications (GSM), Universal Mobile Telecommunication System (UMTS), High Speed Packet Access (HSPA), Evolved High Speed Packet Access (HSPA+), Long Term Evolution (LTE), WiFi, or WiMax technologies.

The telecommunication network 114 may be comprised of node(s) 112, including any or all of access network nodes 112, backhaul nodes 112, or core network nodes 112. The access network nodes 112 may include base stations, node Bs, eNode Bs, or radio network controllers (RNCs). The backhaul nodes 112 may be routers or gateways with Ethernet lines connected to other backhaul nodes 112, to access network nodes 112, to core network nodes 112, etc. Core network nodes 112 may be any nodes 112 of the telecommunication network 114 in a transmission path between two communicating end-points, one or both of which may be a mobile device receiving telecommunication services through an access network node 112.

In various implementations, the node(s) 112 may each be or include a server or server farm, multiple, distributed server farms, a mainframe, a work station, a PC, a laptop computer, a tablet computer, an embedded system, or any other sort of device or devices. An example node 112 is illustrated in FIG. 3 and is described in detail below with reference to that figure.

As shown, the node(s) 112 may also include transmission component(s) 122. The transmission component(s) 122 may include any software components, hardware components, or both for monitoring and managing network resources of their respective node(s) 112 (e.g., cellular resources, backhaul resources, transport resources, core network resources, etc.). For example, an access network node 112 may be equipped with radios for sending and receiving traffic 110 over different bands of frequency spectrum, and the transmission component(s) 122 of such an access network node 112 may include a scheduler for allocating blocks of frequency bands to different mobile devices. The allocation by the scheduler may be based on the QoS class 108 associated with the traffic 110 with each mobile device. The QoS class 108 may be determined based on an application or service associated with the traffic 110 (e.g., voice calling, network browsing, etc.), based on different service categories (e.g., a brand associated with a service contract of a user of a mobile device), or based on a data type of the traffic 110. The scheduler may determine the application, data type, or service category associated with traffic 110 with each mobile device, associate QoS classes 108 with the traffic 110 based on those determinations, and utilize the QoS classes in determining which network resources to allocate to which mobile devices. The scheduler or other transmission component(s) 122 of the access network node 112 may also monitor performance metrics, network configuration, or network fault information and report those performance metrics, network configuration, or network fault information to the SON device(s) 102.

The transmission component(s) 122 of the backhaul nodes 112 and core network nodes 112 may determine the QoS class 108 to associate with traffic on a per-data-connection/service-flow basis rather than on a per-user basis. For a given data connection/service flow, such as a voice call connection, the transmission component(s) 122 of the backhaul node 112 or core network node 112 transmitting the traffic 110 associated with the voice call connection may determine the QoS class 108 for the traffic 110 (e.g., based on the application type—voice call—of the connection). The transmission component(s) 122 may then prioritize among the data packets constituting the traffic 110 based on the QoS class 108 associated with those data packets. In one example, data packets of a given QoS class 108 may be stored in a queue for that QoS class 108, and the transmission component(s) 122 may prioritize transmission over network resources based on queue. The transmission component(s) 122 may also monitor performance metrics, network configuration, or network fault information associated with communicating the traffic 110 and may report those performance metrics, network configuration, or network fault information to the SON device(s) 102.

In various implementations, the transmission component(s) 122 at a given node 112 may monitor and report on any sort of performance metrics, configuration, or fault information which may be indicative of the QoS being provided for traffic 110 associated with different QoS classes 108 at that given node 112. Example performance metrics may include at least one of throughput, delay, scheduling delay, queuing delay, jitter, packet loss, number of user, queue length, retransmission, utilization, usage, or latency. Example network configuration may include at least one of hardware configuration software configuration, parameter configuration, or capacity configuration. Example network fault information may include network alarms or warning. These performance metrics, network configuration, or network fault information, or any subset of them, may be gathered by the transmission component(s) 122 for traffic 110 on a per-QoS-class basis at the given node 112, so that there may be a set of performance metrics, network configuration, or network fault information for each QoS class 108 used by the given node 112, and reported to the SON device(s) 102. In some implementations, different performance metrics, network configuration, or network fault information may be gathered by the transmission component(s) 122 for different QoS classes 108, at different nodes 112, or both.

In addition to monitoring and reporting on performance metrics, network configuration, or network fault information, the transmission component(s) 122 of the nodes 112, may dynamically adjust QoS factors 106 associated with their QoS classes 108. These QoS factors 106 may be used along with the QoS classes 108 to adjust the priority given to traffic 110 of the different QoS classes 108. Examples of QoS factors 106 may include weights, delay budget, maximum bit rate, and minimum bit rate. For instance, traffic 110 associated with a QoS class 108 of ‘1’ may be given a higher priority than traffic 110 with a QoS class 108 of ‘2’, by the effect of that priority difference in allocating network resources may be affected by the QoS factors 106. The transmission component(s) 122 may receive indications of QoS factors 106 determined by the SON device(s) 102 from the SON device(s) 102 and may then update the QoS factors 106 based on the received indications. Those QoS factors 106 are then used by the transmission component(s) 122 in allocating network resources.

In some implementations, the transmission component(s) 122 may receive adjustments to the QoS class 108 associated with traffic 110 either in addition to or instead of the adjustments to the QoS factors 106. Responsive to receiving such adjustments to the QoS class 108 for a part of the traffic, the transmission component(s) 122 may reclassify that part of the traffic 110 with the adjusted QoS class 108.

In a first example, an access network node 112 may be experiencing heavy demand of its network resources. Many mobile devices may be connected to the access network node 112, and some of those mobile devices may be heavily utilizing cellular resource (e.g., by watching streaming video, etc.). The demand may exceed the available network resources of the access network node 112, causing delay or loss in the transmission of some packets. The transmission component(s) 122 of the access network node 112 may assign network resources based on QoS class 108, giving, for instance, higher priority to voice calls than to streaming movies. But even this may result in dropped calls if the QoS class 108 for voice calls is not given sufficient QoS factor. Thus, the transmission component(s) 122 report performance metrics, network configuration, or network fault information for the traffic 110 of the QoS classes 108 of the access network node 112 and receive indications of QoS factors 106 to use in return. The transmission component(s) 122 may then update the QoS factors 106 based on the indications, and the resulting QoS factors 106 may result in the QoS class 108 for the voice calls being given sufficient priority such that the voice calls are not dropped.

In a second example, an access network node 112 may be experiencing low demand of its network resources. It may, for instance, be late at night, with few real-time communications and streaming media sessions. There may be more than enough network resources for the demand. In allocating network resources, however, the transmission component(s) 122 may deprioritize traffic 110 of a lower priority QoS class 108, resulting in a poorer QoS being provided to that traffic 110 than need be under the conditions. To avoid this result, the transmission component(s) 122 report performance metrics, network configuration, or network fault information for the traffic 110 of the QoS classes 108 of the access network node 112 and receive indications of QoS factors 106 to use in return. The transmission component(s) 122 may then update the QoS factors 106 based on the indications, and the resulting QoS factors 106 may result in more equal treatment and better QoS across the board, for all traffic 110 of the access network node 112.

In various implements, the SON device(s) 102 may be associated with an operations support system (OSS) of the telecommunication network 114 or may be an application server or servers of the telecommunication network 114. The transmission component(s) 122 of the node(s) 112 may be configured to report performance metrics, network configuration, or network fault information to the SON device(s) 102 and to receive indications of QoS factors 106 from the SON device(s) 102. In some implementations, the consolidation engine 118 may be a SON component whose purpose to receive and store the performance metrics, network configuration, or network fault information in the performance metrics, network configuration, or network fault information store 116. The performance metrics, network configuration, or network fault information store 116 may be any sort of database, file, or data structure. Also, the performance metrics, network configuration, or network fault information store 116 may be associated with a schema, and the schema may be extended in response to the addition of new SON tools 104 or to the modification of a SON tool 104. In some implementations, the consolidation engine 118 may also filter out redundant or non-utilized performance metrics, network configuration, or network fault information.

The consolidation engine 118 may then automatically provide the performance metrics, network configuration, or network fault information from the performance metrics, network configuration, or network fault information store 116 to one or more of the SON tools 104 on, e.g., a periodic or event-driven basis. In some implementations, the consolidation engine 118 may pass performance metrics, network configuration, or network fault information to different ones of the SON tools 104 based on any or all of a type of node 112 associated with the performance metrics, network configuration, or network fault information, a QoS class associated with the performance metrics, network configuration, or network fault information, a time of day associated with the performance metrics, network configuration, or network fault information, various patterns or thresholds meeting the performance metrics, network configuration, or network fault information, etc. In other implementations, rather than automatically invoking SON tools 104, the consolidation engine 118 may be queried for performance metrics, network configuration, or network fault information by the SON tools 104.

In various implementations, the various SON components of the SON device(s) 102 may be connected by a SON API. The API may be an API for SONs that may be standardized and shared among multiple SONs. When standardized, the API may expose at least one of standardized methods/procedures or standardized parameters, such as the performance metrics, network configuration, or network fault information. In other implementations, the architecture utilizing the API may be standardized among multiple SONs, but the API may be specific to the SON device(s) 102. In addition, the API may include methods for providing data to or for receiving or retrieving data from any of the SON components 104, 116-120, and 124. In some implementations, the API may include methods for alerts or alarms that may be utilized by the SON tools 104 to receive notifications that, for example, a performance metric exceeds a threshold. Also, the API may be a separate SON component or may be methods/processes of other SON components, such as SON components 104, 116-120, and 124, and the API may simply be a logical representation. An example SON API is described in greater detail in Application Ser. No. 13/831,082, which is incorporated by reference above.

Upon receiving or retrieving the performance metrics, network configuration, or network fault information through consolidation engine 118, the SON tool(s) 104 may determine QoS factors 106 for the QoS classes 108 of the nodes(s) 112 based on those performance metrics, network configuration, or network fault information. The SON tool(s) 104 may use or be configured in accordance with a policy of the telecommunication network operator providing different levels of QoS to different classes of traffic 110 in different circumstances. Each policy may comprise or be resolved to a model or rule set associated different QoS factors 106 or weigh-adjustments with different combinations of performance metrics, network configuration, or network fault information, node types, QoS class types, times of day, network conditions, or other sorts of parameters. Upon determining the QoS factors 106 or QoS factor adjustments, the SON tool(s) 104 may provide the QoS factors 106 or QoS factor adjustments to the parameter configurator 120, through, e.g., the SON API.

The SON tool(s) 104 may also each invoke a SON component to perform an action based on the performance metrics, network configuration, or network fault information, invoke an engineering tool based on the performance metrics, network configuration, or network fault information, pass information associated with the performance metrics, network configuration, or network fault information to a SON component, send a notification associated with the performance metrics, network configuration, or network fault information, or generate of a report based on the performance metrics, network configuration, or network fault information. A SON tool 104 may also be invoked by another SON tool 104, and those SON tools 104 may collaborate to determine the QoS factors 106.

In some implementations, the SON tool(s) 104 may comprise different tools 104 for different types of nodes 112, different tools 104 for different times of day, different tools 104 for different network conditions, etc. Alternatively, a single SON tool 104 or set of SON tools 104 may be used for multiple types of nodes 112, times of day, network conditions, etc. with policy and configuration specifying a same or different treatment in view of those differences. For example, the SON tool(s) 104 may determine different QoS factors 106 for different types of node(s) 112 even if performance metrics, network configuration, or network fault information are the same or similar. The SON tool(s) 104 may also determine different QoS factors 106 for different times of day or network conditions when performance metrics, network configuration, or network fault information are the same or similar. Alternatively, similar or same QoS factors 106 may be determined despite differences in type of node 112, time of day, network conditions, etc.

Further, the SON tool(s) 104 may be configured to monitor results of adjustments of QoS factors 106 and to modify its model or rule set based on the monitoring. Such feedback and refinement may utilize machine learning techniques. Alternatively or additionally, the SON tool(s) 104 may make smaller adjustments to the QoS factors 106, gradually increasing or decreasing them over a number of iterations of updates and performance metric reports. Such a gradual approach may improve functioning without introducing other additional performance issues.

Also, in some implementations, the SON tool(s) 104 may adjust the QoS class 108 for the traffic 110 associated with the performance metrics, network configuration, or network fault information. The SON tool(s) 104 may do this instead of or in addition to determining QoS factors 106. Such a QoS class adjustment may also be provided to the node(s) 112 through the parameter configurator 120.

In various implementations, the SON tool(s) 104 may be created or modified by a SON portal 124. The SON portal 124 may be a user-facing component for displaying information and enabling specification of SON tool(s) 104 by users (e.g., personnel of the telecommunication network operator). The SON portal 124 may offer a user interface for textual or graphical specification of a new SON tool 104 or for configuring/updating of an existing SON tool 104. Such a user interface may simply accept textually-specified code for a SON tool 104, or may even allow a user to select graphical representations of SON components (e.g., a graphical representation of the consolidation engine 118) to cause automatic specification of code for accessing the SON component.

As mentioned, upon determining the QoS factors 106 or QoS factor adjustments, the SON tool(s) 104 may provide the QoS factors 106 or QoS factor adjustments to the parameter configurator 120. Upon retrieving or receiving the QoS factors 106 or QoS factor adjustments, the parameter configurator 114 transmits indications of the QoS factors 106 or QoS factor adjustments to the node(s) 112.

Generally, computer-executable instructions include routines, programs, objects, components, data structures, and the like that perform particular functions or implement particular abstract data types. The order in which the operations are described is not intended to be construed as a limitation, and any number of the described operations can be combined in any order and/or in parallel to implement the processes.

FIG. 4 illustrates an example process for determining, by SON component(s), QoS factors for QoS classes of a telecommunication network node based on performance metrics, network configuration, or network fault information associated with communication of traffic of the QoS classes. The process includes, at 402, receiving, by one or more SON components, performance metrics, network configuration, or network fault information associated with communication of traffic of one or more QoS classes by a node of a telecommunication network. The QoS classes may be associated with different applications, different data types, or different service categories. Further, the node may be an access network node, a backhaul node, or a core network node. Also, the performance metrics, network configuration, or network fault information may include at least one of throughput, delay, scheduling delay, queuing delay, jitter, packet loss, number of user, or latency. In some examples, the performance metrics, network configuration, or network fault information are specific to traffic for a specific QoS class. In further examples, the performance metrics, network configuration, or network fault information include multiple sets of metrics correspondingly associated with traffic of multiple QoS classes.

At 404, the SON component(s) determine QoS factors associated with the one or more QoS classes based at least in part on the performance metrics, network configuration, or network fault information. At 406, the determining comprises determining different QoS factors for different times of day or different network conditions. At 408, the determining comprises determining the QoS factors based on a type of the node. At 410, determining the QoS factors based on a type of the node includes determining different QoS factors for different types of nodes.

At 412, the SON component(s) transmit indications of the QoS factors to the node of the telecommunication network.

In some implementations, the SON component(s) may repeatedly perform the receiving at 402, the determining at 404, and the transmitting at 412 to incrementally adjust the QoS factors (e.g., gradually increase weights).

At 414, the SON component(s) may adjust the QoS class associated with the traffic.

FIG. 5 illustrates an example process for reporting, by a telecommunication network node, performance metrics, network configuration, or network fault information associated with communication of traffic of the QoS classes, receiving indications of QoS factors for the QoS classes, and updating the QoS factors based on the received indications. The example process includes, at 502, determining, by a node of a telecommunication network, performance metrics, network configuration, or network fault information associated with transmitting or receiving traffic of one or more QoS classes. The performance metrics, network configuration, or network fault information may include at least one of throughput, delay, scheduling delay, queuing delay, jitter, packet loss, number of user, or latency. The QoS classes may be associated with different applications, different data types, or different service categories.

At 504, the node may report the performance metrics, network configuration, or network fault information to one or more SON components of the telecommunication network.

At 506, the node may receive indications of QoS factors associated with the one or more QoS classes.

At 508, the node may update the QoS factors associated with the one or more QoS classes based on the received indications.

In some implementations, the node may repeatedly perform the determining at 502, the reporting at 504, the receiving at 506, and the updating at 508 to incrementally adjust the QoS factors

At 510, the node may also or instead the QoS class associated with the traffic (based, e.g., on instructions from SON component(s)).

At 512, the node may utilize QoS factored QoS classes in allocating network resources to users.
